Effect of different vehicles in carrageenan suspension on the rate of the inflammatory response of chicks

Este trabalho descreve o padräo de resposta de edema, aumento de permeabilidade vascular e exsudaçäo celular induzidos pela injeçäo de diferentes suspensöes de carragenina nos coxins plantares de 80 pintos machos, de três a quatro semanas de idade. As suspensöes de carragenina 0,5 por cento foram...

Tentativa de infecçäo experimental da pomba-rola (Columbina picui) com Mycoplasma synoviae
A trial to infect the free-flying pigeon Columbina picui with Mycoplasma synoviae

O Mycoplasma sinoviae é patogênico para várias espécies de aves silvestres e domésticas, causando aerossaculite e sinovite. Sua transmissäo ocorre horizontalmente entre galinhas de um mesmo lote, e verticalmente, pelo ovo. A importância de sua transmissäo de aves silvestres para domésticas, ou v...

Proteçäo de galinhas pela cepa vacinal Conn-F de Mycoplasma gallisepticum, na forma liofilizada e como cultura fresca
Protection against Mycoplasma gallisepticum in chickens vaccinated with the Conn-F strain in the lyophilized form or as a broth culture

Estudou-se a cepa Conn-F de Mycoplasma gallisepticum como vacina para galinhas, utilizada na forma liofilizada, com títulos variáveis, e como cultura fresca. A resposta vacinal foi avaliada através da inoculaçäo no saco aéreo da cepa patogênica R de M. gallisepticum aos 28 e 49 dias pós-vacinaçÃ...
